SouthPAN
What is SouthPAN?
- The Southern
Positioning Augmentation Network
(SouthPAN) is a joint initiative of the Australian and New Zealand
governments to provide a Satellite-Based Augmentation System (SBAS)
for Australia and New Zealand.
- SouthPAN early Open Services became live on
26 September 2022.
- SouthPAN is the first SBAS in the
Southern Hemisphere.
How does SouthPAN work?
- Similar to other SBAS systems, the SouthPAN system consists of
a single geostationary satellite and one ground station.
-
Early Open Services will use a single, dedicated,
uplink facility to transmit the data stream to the geostationary satellite.
-
Additional uplink facilities will be deployed to
provide redundancy and support new satellites in the future.
-
Early Open Services will transmit data on the L1
(1575.420 MHz) and L5 (1176.450 MHz) frequencies.
-
Additional satellites will be added to provide
another navigation frequency of 1207.140 MHz.
-
When complete, SouthPAN will include a total of
two satellites in geostationary orbit.
SouthPAN
Service Area
- SouthPAN is intended to provide improved
Position, Navigation, and Timing (PNT) capabilities to End-Users in
Australia and New Zealand.

Do I need
SouthPAN?
- SouthPAN is the first SBAS in the Southern
Hemisphere.
- SouthPAN will enable users with a receiver
that tracks GPS L1 C/A signals to improve their position accuracy to better
than ≤3m in the horizontal and ≤4 m in the vertical (95% confidence
interval).
- SouthPAN will
enable users with a receiver that tracks GPS L1 C/A and L5 signals,
and Galileo E1 and E5a signals to improve their position accuracy to better
than ≤1.5m in the horizontal and ≤2.5 m in the vertical (95% confidence
interval).
- Unless your current gear can do this without
SouthPAN access, you need SouthPAN!
